Previously image processing systems, such as 3 df X's V ο 〇D ο 〇 2 TM graphics card products are scanned line interleaving (SLI) or Metapye/Wicked 3D parallel image setup (PGC), etc. The technology provides for improved image processing performance by using two display cards in a fixed setting that is not modular so that the user can install a second display card. The prior art image processing system uses a dedicated interface and wiring to transmit an analog pixel stream produced by each display card to a single analog pixel stream for output to a single A pixel multiplexing device for a display device. Because the prior art is set to be fixed, the user cannot install and connect an additional display card to the dedicated interface to enhance image processing performance for the single display device. In addition, because the pixel stream is composed of artificial objects of the analog field, it may cause mismatch due to the digits on the respective display cards and the analog converter. Therefore, it is desirable for us to assist the user in completing the installation process of the additional display card, which includes the installation of a multi-bit 1310920 digital connection between two or more display cards to enhance image processing performance.
